摘要
事件相关电位测谎技术(简称ERP)作为近年来兴起的心理测试方式与传统的多道心理测试技术相比有很大的不同:在基本原理方面,事件相关电位测谎是根据被试对相关刺激的脑电反应来判别他与所调查事件的关系,而多道心理测试技术则是根据被试对相关刺激的呼吸和血压的变化来进行评判;在测试内容和程序方面表现为行为样本、评分标准和测试结论上的差异;在效度、信度方面,多道心理测试技术具有优于事件相关电位测谎的信度和效度研究成果。
Event-related Potential(ERP) as a lie detecting technique is a newly-appeared means of psychology test and differs from traditional polygraph techniques in many ways.As to the aspect of theoretical base,ERP judges the relationship between the testee and the event being investigated on the basis of the brain response to the relevant stimulations while polygraph technique is based on transcutaneous electrics,breath and blood pressure.Polygraph technique outweighs ERP in reliability and efficiency.
